The angular response (AR) effect which reduces multibeam backscatter image quality significantly cannot be removed by the traditional AR correction methods effectively. Therefore, the paper puts forward two self-adaptive AR correction methods, namely the AR modeling method and the AR clustering method. The former uses the AR parameters of the average AR curve for modeling and correction, while the latter uses the AR curve of each seabed sediment for AR correction. Both methods overcome the defects of the traditional methods, and improve the image quality obviously. The validities of the methods have been verified by the experiments. [ABSTRACT FROM AUTHOR]
